Phil Yang commented on HBASE-16652:
-----------------------------------

If I am not wrong, we have a default TimeRange in Scan so the tr will not be 
null. But if the Get's range is null, the scan's tr will be null, too. So if we 
set Scan's default value to null, will scan be faster too? Thanks.

> When do performance test in HBASE-16625,  i found it has the very big 
> difference between Append and Increment (append is about 37% faster than 
> increment).
> As [~stack] mentioned in 
> https://issues.apache.org/jira/browse/HBASE-16610?focusedCommentId=15493166&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15493166,
>    append and increment has been unified in server-side,  and they looks the 
> same in client-side. 
> This issue is to figure out why the performance looks different between them.
